Objective: To explore the relationship between aggression and category perception of angry expression in reform school students under social exclusion, so as to provide reference for the reform school students mental health promotion. Methods: In May 2023, 144 students were randomly selected from a reform school in Guizhou Province, and were divided into high and low aggression groups(77 and 67 students) by Aggression Questionnaire. Cyberball game was used to induce social exclusion and acceptance, subjects were divided into high aggressive exclusion group ( n =42), high aggressive acceptance group ( n =35), low aggressive exclusion group ( n =37) and low aggressive acceptance group ( n =30). All the participants completed the discrimination and identification tasks of category perception paradigm, and the relationship between aggression and category perception of angry expression of reform school students under social exclusion was analyzed by using category turning point, identification curve and analysis of variance. Results: The total score of aggression(97.34±8.00) and four dimensions (physical aggression: 29.75± 4.61, verbal aggression:17.19±2.58, anger:22.29±3.66, hostility:28.10±3.54) in the high aggression group were higher than those in the low aggression group(74.10±9.02，21.09±4.98，14.30±2.66，17.16±3.83，21.55±3.88), and the differences were statistically significant ( t =16.38, 10.85, 6.62, 8.20, 10.59, P <0.01). For identifying the turning point of the fear anger continuum, the social exclusion group（2.58±0.07）was significantly smaller than the social acceptance group（2.79±0.07）( F =4.85, η 2=0.07, P < 0.05 ）, and the social exclusion group had a tendency to shift the category boundary to the fear side. For identifying the slope at the angry happiness continuum category boundary curve, the high aggression group (0.63±0.03) was significantly higher than the low aggression group (0.53±0.03)( F =5.38, η 2=0.08, P <0.05). In the fear anger continuum,the high aggression group[(694.86± 78.29 )ms] reacted more quickly than the low aggression group[(660.70±79.86)ms]( F =5.08, η 2=0.05， P <0.05) In the angry happiness continuum, there was no statistical significance of social exclusion and aggression( P >0.05). Conclusions The suggests that social exclusion can lead to hostility attribution bias in individuals, while aggression can make individuals more sensitive to angry expression. The mechanisms by which social exclusion and aggression affect expression category perception are independent rather than interactive. The society should give tolerance and acceptance to reform school students, reduce exclusion and discrimination, and the reform education department should correct the aggressive behavior of reform school students and promote their mental health.

Although geriatric diseases are complicated due to the coexistence of many diseases,they often have a common pathological basis and are closely related to the pathogenesis of deficiency and excess in traditional Chinese medicine.Exploring the characteristics of the pathogenesis of deficiency and excess diseases in the elderly is helpful to keep simplicity and restrain complexity,grasp the law of occurrence and development of diseases in the elderly as a whole,and give full play to the advantages of traditional Chinese medicine in the prevention and treatment of chronic diseases.Based on the fundamental characteristics of deficiency and excess in senile diseases,researcher Hu Jingqing further summarized that"essence deficiency,Yin deficiency,Yang deficiency,qi deficiency,blood deficiency"and"qi stagnation,phlegm dampness,blood stasis,fire and heat,and latent wind"are the most common pathogenesis in the occurrence and development of senile diseases.Among them,deficiency is the basic pathogenesis of senile diseases,especially deficiency of kidney essence.Excess disease is the key pathogenesis of the development and changes of senile diseases.Qi stagnation is often the initial step in the development of senile diseases.Phlegm dampness and blood stasis are the pathological products of"excess due to deficiency"and are also the main secondary pathogenesis of senile diseases.In clinical identification of senile diseases,attention should be paid to grasping the pathogenesis of deficiency and excess and its concurrent changes.

Tongue diagnosis is an indispensable objective basis for TCM diagnosis and treatment of epidemic diseases.To understand its application in an epidemic situation and to support in the diagnosis and treatment of infectious diseases using traditional Chinese medicine,the tongue image APP was implemented in this study to monitor the tongue image features of patients with new coronavirus pneumonia.It has been discovered through practice that the tongue image APP enables medical professionals to objectively,conveniently,quickly,and flexibly collect the patient's tongue image.It has also been discovered through the analysis of the tongue image characteristic data that the tongue image APP can,to a certain extent,objectively reflect the general law of the tongue image characteristics of the new crown pneumonia.According to the tongue image data gathered by the Tongue Image APP,Xinguan pneumonia patients'tongues were typically red,their fur was typically white,yellow,or both white and yellow,and they had a greater amount of thick and greasy fur.Nevertheless,there are still several issues with the Tongue APP application that have been noted:①The consistency of tongue shape and coating was poor;for instance,the inconsistency rate between a thin and fat tongue was as high as 62.96%;②The tongue image analysis index in the APP is still mostly a qualitative index,and the degree of discriminating is insufficient.The results of this study demonstrate that the tongue image information of different ages,sexes,disease classifications,and onset times does not reflect obvious differences and certain rules.③The tongue image characteristic indexes gathered by the tongue image APP are insufficient and do not include information on glossiness of tongue image(such as dark tongue)and tongue state.To promote the adoption of the tongue image APP and better support the prevention and treatment of epidemic diseases by traditional Chinese medicine,we should fully integrate modern advanced science and technology,improve the short videos of tongue coating,quantification of qualitative indicators,comprehensive collection of tongue image characteristic indicators,etc.

Summarize the professor Hu Jingqing's experience in treating pathogenesis of intermingled phlegm and blood stasis by using purgative method.Intermingled phlegm and blood stasis is one of the most important pathogenesis of many difficult diseases in the contemporary era.From the perspective of TCM theory,the purgative method can dissipate phlegm,eliminate blood stasis and resolve masses,which is a suitable method for the treatment in pathogenesis of intermingled phlegm and blood stasis.In clinical practice,the professor Hu Jingqing emphasizes the specific classification of pathogenesis of phlegm and blood stasis in diagnosis,using the purgative methods according to different classifications of"excess heat"and"deficiency cold".And make flexible selections of various purgative drugs in prescription.Last but not least,it is suggested that the purgative method also should not be used as the only treating method.

BACKGROUND: Previous research demonstrated that a homozygous mutation of g.136372044G>A (S12N) in caspase recruitment domain family member 9 ( CARD9 ) is critical for producing Aspergillus fumigatus -induced ( Af -induced) T helper 2 (T H 2)-mediated responses in allergic bronchopulmonary aspergillosis (ABPA). However, it remains unclear whether the CARD9S12N mutation, especially the heterozygous occurrence, predisposes the host to ABPA. METHODS: A total of 61 ABPA patients and 264 controls (including 156 healthy controls and 108 asthma patients) were recruited for sequencing the CARD9 locus to clarify whether patients with this heterozygous single-nucleotide polymorphisms are predisposed to the development of ABPA. A series of in vivo and in vitro experiments, such as quantitative real-time polymerase chain reaction, flow cytometry, and RNA isolation and quantification, were used to illuminate the involved mechanism of the disease. RESULTS: The presence of the p.S12N mutation was associated with a significant risk of ABPA in ABPA patients when compared with healthy controls and asthma patients, regardless of Aspergillus sensitivity. Relative to healthy controls without relevant allergies, the mutation of p.S12N was associated with a significant risk of ABPA (OR: 2.69 and 4.17 for GA and AA genotypes, P = 0.003 and 0.029, respectively). Compared with patients with asthma, ABPA patients had a significantly higher heterozygous mutation (GA genotype), indicating that p.S12N might be a significant ABPA-susceptibility locus ( aspergillus sensitized asthma: OR: 3.02, P = 0.009; aspergillus unsensitized asthma: OR: 2.94, P = 0.005). The mutant allele was preferentially expressed in ABPA patients with heterozygous CARD9S12N , which contributes to its functional alterations to facilitate Af -induced T H 2-mediated ABPA development. In terms of mechanism, Card9 wild-type ( Card9WT ) expression levels decreased significantly due to Af -induced decay of its messenger RNA compared to the heterozygous Card9S12N . In addition, ABPA patients with heterozygous CARD9S12N had increased Af -induced interleukin-5 production. CONCLUSION Our study provides the genetic evidence showing that the heterozygous mutation of CARD9S12N , followed by allele expression imbalance of CARD9S12N , facilitates the development of ABPA.

The stability and pharmacokinetic properties of hyaluronic acid-modified asparaginase (Asp) self-assembled bionic nanocapsules (ASNCs) were preliminarily investigated. ASNCs were prepared by molecular self-assembly method to investigate their morphology, particle size, zeta potential and antitrypsin stability. After intravenous injection of free Asp and ASNCs, rat plasma samples at different times were taken to determine Asp activity. Pharmacokinetic parameters were calculated by DAS pharmacokinetic software. The particle size of ASNCs was (99.17 ± 0.21) nm and the potential was -(13.13 ± 0.60) mV. In trypsin solution, ASNCs showed more excellent stability. The area under the activity-time curve (AUC0-48 h) of ASNCs was about 2 times higher than that of Asp; the mean residence time (MRT0-48 h) was about 1.7 times higher than that of Asp, and the bioavailability was 195% of Asp. The results showed that ASNCs could improve the stability and bioavailability of Asp against trypsin and prolong the circulation time of Asp in vivo.

The aim of this study was to investigate the in vivo pharmacokinetic behavior characteristics and in situ intestinal absorption characteristics of the evodiamine lipidic nanoparticle in rats. Evodiamine lipidic nanoparticle was prepared by the solvent evaporation methods. The particle size and zeta potential of evodiamine lipidic nanoparticle were measured by dynamic light scattering analysis. Male SD rats were divided into two groups randomly. Each group was given single dose of evodiamine and evodiamine lipidic nanoparticle by gavage at evodiamine dose of 250 mg/kg,respectively. The blood samples were collected at scheduled time points. The content of evodiamine in plasma samples was determined by high performance liquid chromatography (HPLC) method. The main pharmacokinetic parameters of evodiamine and evodiamine lipidic nanoparticle were calculated using DAS 2.1.1 software. Moreover,the single-pass intestinal perfusion model was also established in rats to investigate the in situ intestinal absorption characteristics of evodiamine lipidic nanoparticle. The mean particle size and mean zeta potential of evodiamine lipidic nanoparticle were 180.10 nm and -17.90 mV,respectively. The area under the curve of evodiamine and evodiamine lipidic nanoparticle were (862.60±14.03) and (4084.31±17.21) μg/L·h,respectively,and the peak concentration were (163.40±13.27) and (616.90±21.04) μg/L,respectively. Moreover,the absorption of evodiamine lipidic nanoparticle was significantly higher than that of evodiamine in each segment of intestinal tract in rats (P<0.05). The absorption of evodiamine lipidic nanoparticle in colon was better than those of evodiamine lipidic nanoparticle in stomach,duodenum,jejunum and ileum. The absorption rate constant of evodiamine lipidic nanoparticle in stomach,duodenum,jejunum,ileum and colon were (45.10±6.08)×10-5,(48.20±1.21)×10-5,(22.10±3.18)×10-5,(59.10±1.21)×10-5 and (90.00±3.85)×10-5 s-1,respectively,and the effective permeability coefficient in duodenum,jejunum,ileum and colon was (44.10±0.51)×10-5,(17.21±0.77)×10-5,(35.36±0.31)×10-5 and (40.33±0.34)×10-5 cm/s,respectively.All in all, evodiamine lipidic nanoparticle remarkably improved the in situ intestinal absorption of evodiamine in different segments of the intestinal tract in rats and its oral bioavailability in rats.

Although progress has been indeed made by nanomedicines, their efficacies for cancer treatment remain low, consequently leading to failures in translation to clinic. To improve the drug delivery efficiency, nanoparticles need to change size so as to fully utilize the enhanced permeability and retention (EPR) effect of solid tumor, which is the golden principle of nanoparticles used for cancer treatment. Herein, we employed cationic small-sized red emission bovine serum albumin (BSA) protected gold nanocluster (AuNC@CBSA, 21.06 nm) to both load indocyanine green (ICG) and act as imaging probe to realize theranostic. Then AuNC@CBSA-ICG was fabricated with negatively charged hyaluronic acid (HA) to form AuNC@CBSA-ICG@HA, which was about 200 nm to easily retain at tumor site and could be degraded by tumor-specific hyaluronidase into small nanoparticles for deep tumor penetration. The HA shell also endowed AuNC@CBSA-ICG@HA with actively targeting ability and hyaluronidase-dependent drug release. Furthermore, the quenching and recovery of fluorescence revealed the interaction between ICG and carrier, which was essential for the investigation of pharmacokinetic profiles. No matter or , AuNC@CBSA-ICG@HA showed markedly anti-tumor effect, and could suppress 95.0% of tumor growth on mice breast cancer model. All results demonstrated AuNC@CBSA-ICG@HA was potential for breast cancer therapy.

Objective To investigate the clinical and molecular genetic characteristics of hypermethioninemia caused by methionine adenosyltransferase deficiency. Methods The clinical data and related gene analysis of hypermethioninemia caused by methionine adenosyltransferase deficiency in 3 children were retrospectively analyzed. The core pedigree analysis was carried out. Results Three children (2 boys and 1 girl) aged from 5 months to 3 years, were from 3 unrelated families. All of them had no family history. One case was found in neonatal screening. One case was onset with pathological jaundice at 1 month old. Another case was found due to tremor and growth retardation at 2 years old. Blood amino acid ester acyl carnitine spectrum analysis showed that all of them had significantly elevated levels of methionine at 134.50-790.67 μmol/L. All children had MAT1A mutation in methionine adenosyltransferase gene. One case was heterozygous mutations with third exon c.274T>C and seventh exon c.895C>T mutation; one case had sixth exon c.757G>A homozygous mutation; and another case had seventh exon c.791G>A homozygous mutation. The core pedigree analysis showed that the mutations were from theirs parents respectively. Conclusions For children with neurologic impairment, methionine metabolic disorders should be considered. Blood amino acids and gene analysis are important methods for confirmation of the diagnosis. Neonatal screening is an effective way to detect this disease.
